but does not care about connection options. If you rely on specific IP addresses etc., use the
M(docker_container) module to ensure your containers are correctly connected to this network.

notes:
- When network options are changed, the module disconnects all containers from the network, deletes the network, and re-creates the network.
It does not try to reconnect containers, except the ones listed in (I(connected), and even for these, it does not consider specific
connection options like fixed IP addresses or MAC addresses. If you need more control over how the containers are connected to the
network, loop the M(docker_container) module to loop over your containers to make sure they are connected properly.
- The module does not support Docker Swarm, i.e. it will not try to disconnect or reconnect services. If services are connected to the
network, deleting the network will fail. When network options are changed, the network has to be deleted and recreated, so this will
fail as well.
